            <td>The number of consecutive failed heartbeat RPCs until a heartbeat target is marked as unreachable. Failed heartbeat RPCs can be used to detect dead targets faster because they no longer receive the RPCs. The detection time is <code class="highlighter-rouge">heartbeat.interval</code> * <code class="highlighter-rouge">heartbeat.rpc-failure-threshold</code>. In environments with a flaky network, setting this value too low can produce false positives. In this case, we recommend to increase this value, but not higher than <code class="highlighter-rouge">heartbeat.timeout</code> / <code class="highlighter-rouge">heartbeat.interval</code>. The mechanism can be disabled by setting this option to <code class="highlighter-rouge">-1</code></td>
